VHP Series Four xCooled Cylinder Head

Experience increased uptime, reliability, and extended lifecycle intervals with INNIO’s VHP* xCooled cylinder head upgrade. Offering enhanced cylinder head cooling by improving the flow of coolant to critical cylinder head components, the xCooled head has shown proven field-tested results operating at sites with high LHV fuels. The xCooled cylinder head is offered as a direct replacement for existing Series Four* GSI cylinder heads, aligning well with top-end and bottom-end overhauls.

What can this upgrade do for you?

  • Improved reliability when operating on high BTU fuels. Enhanced cooling at the exhaust valve and guide reduces component temperatures up to 40%, lowering thermodynamic stresses in critical components.
  • Extended intervals lead to more time between overhauls, which increases uptime and reduces operating cost. Up to 33% longer intervals between top-end overhauls; 32,000** hours on an L7044GSI engine operating up to 1,680 BHP @ 1,200 RPM continuously.

**Intervals may vary depending on factors such as fuel quality, maintenance practices, and operating conditions. Engine

configuration must be verified for upgrade opportunity.
